Application filed July 27, 1915. Serial No. 42,145.

To all whom it may concern:

Be it known that I, IsArAH I. DAVIS, Jr., a citizen of the United States, residing at Concord, in the county pf Oaharrus' and State of-North Carolina, have invented new and useful Improvements in Label-Gummm Devices, of which the following is a specification.

"The invention hereinafter described and claimed and illustrated in the drawings herewith, relates to a machine for gumrning operated device, it will be understood that I do not limit myself to this, as the device may, of course, be power-operated, and still be within the scope of my invention.

In the drawings herewith,

Figure 1 is a view in front elevation of the machine.

Fig. 2 is a view in plan of the front portion of the-machine.

Fig. 3 is a view in side elevation of the machine in position for use, portions thereof being in section.

Fig. 4 is a detail view in side elevation of the gum roll carrier.

Fig. 5 is a detail view in front elevation of a portion of the gum roll, to show its bearin and driving means.

%ig. 6 is a detail view in side elevation of the delivery table or rack.

Fig. 7 is a view of the machine in side elevation showing the machine in storage or non-usable position.

Referring to the drawings by numerals, like numbers indicating like parts in the several views, 10 designates the adhesive tank or container which is of generally rectangular shape and formed of any suitable material, preferably metal.

The said tank 10 has a flat bottom 11, in order that, as shown in Fig. 7, it may be stood upright when not in use and the adhesive, which will flow to the bottom thereof, conserved. lihe said tank may, if desired, be provided with fastening lugs 10 as shown in Fig. 1, by which it may be secured to a counter or bench, these lugs being shown as open at one side so that they may be slipped into engagement with suitable screws or fastening means.

The general contour and outline of the container or tank 10 is rectangular, as stated, but one of its walls 11 is extended, and upwardly curved at 12, so as to form, with the side walls 13, a well 14 as shown in Fig. 3.

The opposed wall 15 of the container, is, through a portion 16, of its length inclined, as shown, to form a chute or label runway, down which the labels will slide to the adheslve applylng instrumentalities now to be described, the chute having on each side upstandmg flanges or wings 17 to prevent the label leaving the runway as it slides down.

Said side walls 13 extend somewhat beyond the container proper, and an end partition 18, preferably curved to conform to the gum roll, stops communication between the container and well 14, except for the feed slot 19 in the end partition, which, when the device is in the operative position shown in Fig. 3, permits the adhesive to flow to the well 14 formed by the extended and upwardly curved wall 11, hereinbefore referred to, in sufficient quantity, the bulk remaining in the container or tank and feedin out at intervals on the principle of the wel -known self-feeding ink wells, and the like.

Said extended side walls 13 form sup ports for the adhesive-applying instrumentalities, which comprises a frame made up of the side plates 20, having clips 21 which engage the extended side walls 13; said side plates 20 being coupled by the transverse bar 22, which gives a rigid frame and serves as a handy means by which it may be lifted out or placed in position. Said side plates 20 are provided with the bearings 23, which, as herein shown are of the open type and adapted to receive the gudgeons 24 of a gum roll 25 of such dimensions, that, when mounted in the bearings 23, said roll will dip in the adhesive of the well 14 formed by the extended curved wall and the side walls of the tank, hereinbefore described.

Mounted in open bearings formed in the side plates 20 just above the gum roll 25 is a gripper element 26, shown in the present instance in the form of star wheels spaced from one anothe and touching with their points the gum roll 25, springs 27 being provided at each end of the gripper element to hold it always in place in the bearings and in light gripping contact with theroll, so

- gripper 26 is a pic gers 32 of light sprin through a suitable aperture in t e side plate 20. Said turn button 28 serves not only as a means for driving the roller, but also locks it and the frame formed by the side plates 20 and bar 21 in place o as to prevent accidental displacement thereof. By simply unscrewin the turn button, the frame may be remove to permit refilling of the tank 10,

and both rOll 25 and ipper 26 disassembled for the purpose of c caning.

It will beseen on reference to Fi 3 that that chute or runway formed by t e sloping wall 16 delivers to the bite of the roll 25 and gripper 26, o that a label dropped face upward on the runway will slide into the blte of the roll and gripper and be gummed on its underside as the roll 25 1s operated to drive the label through. The star wheels of the gripper 26 touch the label and gum roll only at separated points, and all danger of smearin the rip er with the face of la els is elimina% e d i On the deliver side of the roll 25 and h-ofl" table for the gummed labels, said table being formed preferably of a clip 30 which is removably mounted on the end of the upwardly curved wall 12 and has extending therefrom a curved wall 31 WhlCh extends rearwardly to the roll 25 forming a shield to close the well 14 against dirt and the like. Secured to said shield 31 are finwire which curve rearwardly and, upwar 1 from the clip 30 and then continue straig t to the gum roll on which the rest with slight spring pressure, said r0 1 being preferably ooved at 33 to form seats for the ends of t e fingers.

This construction gives an open table or rack to which the ummed labels are delivered and from which they may. be readily removed, the open rack permitting the ready grasping of such labels, and the rearwardly and upwardly curving fingers give a clearance space for the fingers in removing a gummed label from the table.

The device may, as shown in Fig. 7, be stood on endwhen not in use, allowmg the adhesive to drain back out of the well into the body of the tank, and the curved wall and soiling 12 will to some extent cover and protect the gumming instrumentalities from dust and dirt.

The present embodiment shows a manually-operated device of: small size for desk or counter use, but it will be obvious that the construction ma be of such dimensions as to demand powerriven gumming mechanism,

deterioration fora long time owing to the fact that it is not exposed to the air and is protected at its delivery point to the gum roll, that it will not become contaminated by dirt or foreign particles. Furthermore, the construction is such that the gumming instrumentalities may be quickly removed for replenishing of the tank and readily disassembled for cleaning, the construction being such that no mechanical skill-is necessar to assemble and disassemble the parts.

t is obvious that changes in structure may be made and mechanical expediencies other than those disclosed adopted in working out my invention without departing from the principles thereof.

I claim; I
